Description

Technical Field

[0001] This utility model relates to the field of steel bar processing equipment technology, specifically a precision rib clamping device for a steel bar threading machine. Background Technology

[0002] A rebar threading machine is a specialized piece of machinery for processing and cutting rebar. It can be used efficiently on construction sites, bridge projects, and other construction sites. This equipment is simple and convenient to operate, and boasts high precision and efficiency, significantly improving construction progress and quality. The specific working principle of the rebar threading machine is as follows: the rebar to be cut or connected is conveyed to the worktable via a conveyor belt. Then, the appropriate cutting mode, such as bevel cutting, straight cutting, and bent cutting, is selected through the control panel. The machine will automatically perform the cutting. Simultaneously, parameters such as the cutting length and angle can be set through the control panel to ensure safe and precise cutting of the rebar.

[0003] With the increasing demands of engineering projects and the improvement of construction techniques, the requirements for rebar threading machines are becoming increasingly stringent. In order to improve the accuracy of rebar threading, reduce energy consumption, and ensure good safety performance, a precision clamping device for rebar threading machines is needed to fix the rebars. However, existing precision clamping devices for rebar threading machines suffer from unstable clamping force during operation, which can cause the rebars to slip or move during processing, thus affecting the processing quality of the rebars. Furthermore, existing precision clamping devices for rebar threading machines are usually connected to the rebar threading machine by fixing bolts, which makes it impossible to quickly install and disassemble the device, reducing its convenience.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 As shown, a precision clamping device for a rebar threading machine includes a worktable 1. The worktable 1 facilitates the placement of rebars. A base 2 is fixed to the top of the worktable 1, which, in conjunction with a clamping block 3, allows for clamping of the rebars. The clamping block 3 is slidably connected to the top of the worktable 1, facilitating the fixation of the rebars. A groove 4 for limiting the movement of the clamping block 3 is provided on the top of the worktable 1. A threaded rod 5, rotatably arranged laterally on the inner wall of the worktable 1, allows for the movement of a movable block 7, thereby... To facilitate clamping the reinforcing bars, the clamping block 3 is fixed with a handle 6 at one end of the threaded rod 5. The handle 6 facilitates the rotation of the threaded rod 5. A movable block 7 is fixed at the bottom of the clamping block 3, and the inner wall of the movable block 7 is threadedly connected to the outer side of the threaded rod 5. The movable block 7 facilitates the movement of the clamping block 3. A fixed frame 8 is fixed on the inner wall of the worktable 1. The fixed frame 8 facilitates the fixing of the connecting mechanism 9 to the worktable 1. The fixed frame 8 contains the connecting mechanism 9, which facilitates the connection of the main body to the reinforcing bar threading machine.

[0021] The connecting mechanism 9 includes a limiting block 91 fixed to the inner wall of the fixed frame 8. By setting the limiting block 91, the clamping plate 92 can be easily limited. The clamping plate 92 is slidably connected to the outer side of the limiting block 91. By setting the clamping plate 92, the workbench 1 and the rebar threading machine can be easily clamped and fixed. The inner wall of the fixed frame 8 is rotatably connected to a vertically arranged screw rod 93. By setting the screw rod 93, the clamping plate 92 can be easily driven to clamp the rebar threading machine. The bottom end of the screw rod 93 is fixed with a turntable 94. By setting the turntable 94, the screw rod 93 can be easily driven to rotate.

[0022] A protrusion 10 is fixed on one side of the clamping block 3, and a limiting groove 11 for limiting the protrusion 10 is provided on one side of the base 2. The protruding length of the protrusion 10 is greater than the gap left when the base 2 and the clamping block 3 clamp the reinforcing bar. By setting the protrusion 10 and the limiting groove 11 to work together, it is easy to avoid the clamping block 3 and the base 2 not fitting properly, which would cause the reinforcing bar to shift during operation. Arc-shaped reinforcing bar through holes 12 are symmetrically provided on one side of the base 2 and the clamping block 3, and a certain gap is left when the base 2 and the clamping block 3 clamp the reinforcing bar. The gap is provided on the upper and lower end faces of the rebar through hole 12, with several grooves distributed vertically and horizontally. The vertical grooves divide the rebar through hole 12 into several segments. When the base 2 and the clamping block 3 clamp the rebar, there is a certain gap, which can ensure that the rebar to be threaded is adapted to a certain diameter within a certain range, improve the adaptability of the precision clamping device, and prevent the rebar from rotating during the threading process. The pressure is distributed to multiple plates by the vertical and horizontal grooves, and the wear rate of each plate will be slowed down, thereby extending the life of the precision clamping device.

[0023] The bottom of the workbench 1 is fixed with four sets of vertically arranged sleeves 13. The sleeves 13 are used to limit the position of the support legs 14. The inner walls of the four sets of sleeves 13 are slidably connected to the support legs 14. The support legs 14 are used to support the main body. The inner walls of the support legs 14 are fixed with horizontally arranged springs 15. The springs 15 are used to limit the position of the buckles 16. One end of the springs 15 is fixed with the buckles 16. The buckles 16 are used to fix the position of the support legs 14. The inner walls of the sleeves 13 are provided with limiting holes 17 for limiting the buckles 16. There are five sets of limiting holes 17.

[0024] Working Principle: In use, the turntable 94 is rotated, which drives the lead screw 93 to rotate. The lead screw 93 drives the clamping plate 92 to connect the main body to the rebar threading machine. The sleeve 13, support leg 14, spring 15, buckle 16 and limiting hole 17 work together to support the main body. At the same time, the position of the support leg 14 can be adjusted so that the device can work with rebar threading machines of different heights. Then, the rebar to be threaded is placed on the workbench 1. Then, the handle 6 is rotated, which drives the threaded rod 5 to rotate. The threaded rod 5 drives the movable block 7 to move. The movable block 7 drives the clamping block 3 to slide along the slide groove 4. The clamping block 3 clamps the rebar. The protrusion 10 works with the limiting groove 11 to prevent the clamping block 3 from not fitting properly with the base 2, thus preventing the rebar from shifting during operation. The rebar through hole 12 prevents the rebar from rotating during the threading process, improving the convenience of the main body.
